[Comparison] AMD Ryzen 7 5800U vs Ryzen 5 5500U – We have a new #1 contender in the ULV space

Processors are becoming quite powerful. Now, a 15W unit can output as much performance as a desktop model from previous generations. Today we will test two of these new 15W CPUs from AMD, which are part of the 5000U-series.

However, the Ryzen 5 5500U that we have here still uses the older Zen 2 architecture, along with its buddies, the Ryzen 3 5300U and the Ryzen 7 5700U. Despite the CPUs being from different price brackets, this comparison can serve as a good experiment about how much has the new architecture improved the ULV space.

CPU benchmarks

Starting with the 3D Rendering benchmark with Cinebench 20, the Ryzen 7 5800U was ahead with a lead of about 41%. Moving over to the 2D Rendering test, the Ryzen 7 was faster again, being more than two seconds faster.


Unsurprisingly, the Ryzen 7 5800U was faster both in 3D and 2D Rendering, with huge leads in both. The level of performance that the Ryzen 7 offers is insane, being able to handle heavy workloads, while not consuming a lot of power, improving the battery life. The Ryzen 5 5500U, on the other hand, offers snappy performance while also being able to handle video rendering, albeit not on the level of the Ryzen 7 5800U or the H-series chips. If you just need a daily driver, the Ryzen 5 is a good CPU that can do a lot for the price that it is asking, while the Ryzen 7 does charge a premium for itself.
